Description

The OHT is an outdoor humidity and temperature transmitter which measures the humidity and temperature of air.

The OHT converts the measurements into standard signals of 0-10 Vdc or 4-20 mA.

Available with or without display indicating both Temperature and Humidity on one display.

Ranges and humidity parameters are selectable via dip switches.

 

E-paper Display

The display show the actual value of each parameter, Humidity (rH) + Temperature (T).

The display is an E-Paper display that reflects light just as regular paper, therefore the display is a passive (non-luminating) display.

Thin, light, flexible, good contrast, low energy consumption and no light reflections.

Easy reading even with high ambient brightness.

E-Paper displays only need energy when the display contents change.

Optics and readability are significantly better than with monochrome LCD´s or other bi-stable systems.

High readability independent of the reader's perspective.


Features

• Humidity and Temperature outputs, 2 x 4-20mA or 2 x 0-10VDC

• Available with or without display

• Humidity output 0-10 Vdc or 4-20 mA

• Temperature output 0-10 Vdc or 4-20 mA

• As an option passive direct temperature output can be made to order.
PT1000, PT100, NTC 10K, NTC 20K, NTC 1.8K, NI1000 etc (By Request)

• Humidity tolerance ± 2% at 20 to 80% rH

• Temperature tolerance ± 0,3K (+5°C to 60°C) + 1.5% f.s
